MATERIAL TRANSFER HOSE

The wire. Both are 10 bar over 51 mm to 152 mm, but this one carries spiral steel wire and a conductive copper wire, where the cement version is cord only — so this hose holds its shape under pressure and earths static.

For a blown line, yes; for a line that is sucked, no. The spiral wire here holds the bore under pressure and against a shutdown, but a true suction duty asks for the suction and discharge build at the same 51 mm or 76 mm bore.

10 bar working with 30 bar minimum burst, on a 51 mm bore, a 67.4 mm outside diameter, a 4.0 mm wear layer and 1.73 kg per metre, on a 61 m coil.

152 mm at 6 inch, with a 178.6 mm outside diameter, a 6.0 mm wear layer and 7.27 kg per metre, supplied on a 30.5 m coil.

That is what the conductive copper wire is for: a path the length of the hose for charge generated by dry product moving fast. The rating is 10 bar across all six bores, with a 4.0 to 6.0 mm layer against the wear.

Yes — the 102 mm code at 4.26 kg/m is the usual size, and the 127 mm code at 5.55 kg/m takes a higher fill rate on the same 10 bar. Both come on a 30.5 m coil above 4 inch.

Because the material moves fastest in the largest bore. The layer is 4.0 mm at 51 and 64 mm, 5.0 mm at 76 to 127 mm and 6.0 mm at 152 mm, so the wall grows with the duty rather than staying nominal.

Because the product is thrown to the outside wall at every change of direction, and the wear layer is what absorbs it. On the 76 mm code with a 5.0 mm layer a swept support rather than a tight clamp is what keeps the layer working.

One coil or cut lengths from a metre across the six bores from 51 mm to 152 mm. The 61 m coil covers the 2 to 4 inch codes and the 30.5 m coil the 5 and 6 inch codes, so a mixed order ships as two coil sizes.

Per metre by bore and by layer: 1.73 kg/m at 2 inch against 7.27 kg/m at 6 inch. Send bore, material, conveying rate, blower pressure and destination for a firm figure.
